Question

Light enters from air to water having refractive index 4/3. Find the

absolute refractive index of a medium if the speed of light in vacuum is

3x10^8m/s​

Answer 1

Answer:

refractive index = speed of light in vacuum by speed of light in water .

try to solve this equation by this formula by placing it given values in the correct place .

2.25× 100000000m/sec

I hope this will helps you .
